Diseases of hair can lead to hair loss. They both are interrelated and they shouldn’t be considered separately.
Common hair loss causes:
There are many causes of hair loss and they vary from person to person. There is no single factor which can be marked out as a common cause of hair loss worldwide.
The two types of hair loss diseases:
Generally we can divide the major causes of hair loss in to two main groups which includes: the temporary effect and a prolonged effect. Hair loss diseases which have a prolonged effect can also be triggered by genetics.
a.) The temporary effect :
The temporary diseases of hair loss can be cured by medications and treatments. They are generally for a short period of time. Child birth, using birth control pills, etc are some of the causes that cause temporary hair loss.
b.) Prolonged hair loss diseases :
In prolonged diseases of hair loss, treatments with drugs are usually in effective. If the treatments don’t work then the only option is to perform surgeries like hair transplantation. These types of cases require long term treatment.
Other factor that causes hair loss is hormonal imbalance. Hormonal imbalance causes a major hair disease and if untreated, it can cause pattern baldness.
Relation between hair diseases and hair loss:
A relation has been found between hair diseases and hair loss. A particular type of hair loss is mostly associated with a particular type of hair disease. Excessive use of hair treatments and styling products can lead to acquired hair shaft defects. Likewise, an unhygienic scalp can cause infectious diseases leading to hair fall.
The common causes of hair loss diseases:
The most common causes of hair disease leading to hair fall include: Hormonal imbalance, Ailment, Faulty hair styling, inadequate diet.
In men the major cause of hair loss disease is hormonal imbalance. In males, there is a key hormone called testosterone which gives secondary sexual characteristics to men but on other hand its excess also causes male pattern baldness. This hormone increases the hair loss.
In hair follicles there is an enzyme called 5 alpha reductase which converts testosterone to dihydrotestosterone (DHT). DHT is the most potent androgen which causes male pattern baldness. This disease is very common among men.
In women, DHT is not a major hormone causing hair loss. The key hormone causing sudden hair loss in women is thyroid hormone. Thyroid hormone is secreted by thyroid gland, so a hyperactive thyroid gland or a hypoactive thyroid gland can cause hair fall.
Imbalance in thyroid hormone leads to hair fall because this hormone has a influence on metabolism of scalp proteins, lipids, minerals and carbohydrates, so its excess or deficiency can cause hair fall.
Hormonal imbalance can also occur during pregnancy which causes hair fall. During pregnancy, the level of estrogen increases. This causes the hair follicles to go in to anagen growth phase. After the birth of child, the level of estrogen falls rapidly. At this time, a large number of hair follicles go into catagen phase and then the hair starts to fall gradually.
Hair loss can also occur after the pregnancy period is over. This type of hair loss is temporary in nature. If the hair loss continues for months after pregnancy, then there could be hormonal imbalance in the body which is causing hair fall. If there is chronic hormonal imbalance, then a proper treatment is required to stop the hair fall.
The hair follicles can go in to resting phase during serious ailments like severe infection, high fever, or flu. This causes excessive hair fall and this condition is called as telogen effluvium. This is a temporary condition and the hair fall stops when the disease is corrected.
There are various cancer treatments during which there is gradual loss of hairs. Cancer treatments prevent hair fiber growth and it also causes thinning and breaking off of hairs.The hair fall usually starts within one to three weeks after beginning of chemotherapy. The patient can lost up to 90 percent of hairs on scalp.
Faulty hair styling:
Many hair styling techniques have been introduced these days. Some of these techniques are not good for hairs and it causes hair fall. For example, in braiding cornrowing the hairs are tied so tightly that it can pull the hairs from their hair follicles causing hair loss. This type of hair loss is called traction alopecia because it occurs due to excessive pull on the hairs. It is better to make those hair styles that does not harm your hairs and makes you look good as well.
Many cosmetic treatments are available in market these days which helps you to make your hairs look good. But most of these treatments are harmful for hairs. The treatments include coloring, bleaching, or hair straightening like chemical relaxing. These treatments can cause hair fall if not done in a proper manner.
Many people especially women go on crash diet so that they can lose weight rapidly. These diets are mostly low in protein, minerals and vitamins. A balance diet is very important for hairs. In the absence of a balance diet, the hairs start to fall because they don’t get the necessary vitamins, minerals and proteins for growth to occur.
Some people have abnormal eating habits. Such people mostly eat junk food which does not have proper nutrients. Such diet causes excessive hair fall.
It is important that you take good care of your hairs so that the hair fall does not occur. if hair fall begins, it is necessary to stop it as early as possible before you lose all your hairs. Many hair loss products are available in the market to treat hair fall.
